Congratulations on your baby cockatiels, I bet they are cute....or at least will be when they get a little bigger and have feathers.
Years ago I used to have zebra finches and they had quite a few "litters" of baby finches. It was always fun to watch them grow from itty bitty, tiny, helpless bald little creatures to the beautiful little birds they became. It also amazed me at how quickley those changes occured.
Good luck with your babies......hope they thrive. I too would love to see pictures of them.
